If a registered domain is allowed to expire, the domain enters a grace period of 30 days.
After 30 days, the domain enters redemption period. While the domain can still be renewed by the previous owner, there is now a cost in doing so:
- gTLDs (.com .net .biz .info .org): NZD$115
- .nz TLDs (.nz .co.nz .net.nz .org.nz): NZD$29
The redemption fees above are in addition to any domain registration / renewal fees. Redemption periods vary from 30-90 days for different TLDs.
During the grace and redemption periods, no third-party is able to register the domain. Only the previous registrant can renew until the redemption period has closed.
If a domain remains unregistered beyond the redemption period, it is usually locked from registration for a short time and then released as an available domain.
